The new Pokémon Go Halloween event — which increases the spawn rates for certain spooky-themed Pokémon and increases the rate at which players earn candy — is now live. A quick glance at Twitter and Reddit show that the feedback has been pretty positive overall.

That's good news for Niantic, the company that developed Pokémon Go. It's no secret Pokémon Go's monthly active players have been decreasing over time, so Niantic is likely looking for new ways to keep its millions of monthly players engaged for as long as possible. Based on the feedback, these types of special in-game events might be the way to go.
